month 5 consists of weeks 18-22
month 6 consists of weeks 23-27
month 7 consists of weeks 28-31
month 8 consists of weeks 32-35
month 9 consists of weeks 36-40
Hope this helps you out. Also do get this book if you dont have it- its very informative. Good Luck & keep :-))

yeah the way Mary just did it is what you should go by if you want to go by a regular 9 month pregnancy. Dividing by 4 to get your months does work, but that tells you how many lunar months you are. There are 10 lunar months in a pregnancy. But only 9 going by calendar months. I prefer going by calendar months even though it is more difficult just because that is how I date everything else, I don't want to date my pregnancy differently. It is easier though to go by lunar months.
